Police conducted a field sobriety test and determined the 22-year-old was under the influence, officials said. Ryan was arrested on a felony DUI; however, local authorities reduced her offense to a misdemeanor.

Ryan has talked in the past about surviving an abusive relationship. Last year the Disney star opened up to Teen Vogue about a friendship that turned out to be incredibly unhealthy.

"I wasn't dating this person. This person considered themselves my best friend," she told the publication. "We also had a professional relationship and it was such emotional manipulation to the point where it became physical, and it stopped before it got too far."

She added, "The second someone puts their hand on you, a boundary has been crossed. If anyone is feeling manipulated or abused, that's the best it's going to get and you have to fight for yourself now."
